Tuna graveyard

August 2006, Greenpeace activists from the Rainbow Warrior form a symbolic 'tuna graveyard' with mock crosses inside a tuna ranch in Cartagena, Southeast Spain. They call for the immediate closure of the Mediterranean bluefin tuna fishery until it can be properly managed and the adoption of urgent measures, including the establishment of a network of marine reserves to protect 40% of the Mediterranean Sea and regenerate its fish stocks.
